   runut · Effects — Radii, Shadows, Motion
   ------------------------------------------------------------
   The brand is unmistakably ROUNDED — the app icon is a ~22%
   superellipse-ish square, every letter terminal is soft.
   So radii run generous and shadows are soft & plum-tinted
   (never neutral-gray), which keeps depth feeling warm.
